Abstract

The invention relates to a scanned-slot x-ray imaging system, having a first collimator and a second collimator arranged in a first distance (a) and a second distance (b), respectively, from a radiation source and each provided with a slot and a detector located under the second collimator slot, said slot of said second collimator being wider than the said slot of said first collimator and said detector under the second slot is wider than the first collimator slot and the second collimator slot. The slot of said second collimator has a width (y') not less than a safety margin and the product of the width (x) of the slot of said first collimator and said second distance (b) divided with the said first distance (a) for allowing a misalignment with respect to a central symmetry line of said slots.
